Moscow High-Voltage Networks

About the Branch

Moscow High-Voltage Networks (MHVN) is a branch of Moscow United Electric Grid Company, PJSC one of the largest distribution grid companies in Russia, carrying out transmission of electric energy in Moscow region.

The branch was created on January 1, 2016 in accordance with the decision on reforming the power grid sector by unifying the asset management system and creating a single point of responsibility for operational and technological maintenance of power transmission lines, substations with 35-220 kV equipment, and organizing rescue and recovery operations in Moscow. The creation of the branch allowed to combine all substations, aerial transmission lines with voltage of 35-220 kV and cable lines with voltage from 110 to 500 kV in Moscow, which first became operational in 1922.

Main Activities

The main type of activity of Moscow High-Voltage Networks is provision of paid services of transmitting electrical energy to consumers in Moscow. The MHVN team operates feeding centers of 35-220 kV for technological connection of consumers, and carries out a range of activities on operational servicing and maintenance of equipment and facilities at the feeding center, operating aerial and cable lines with the voltage of 35-500 kV. The staff of the branch assess project solutions for construction and reconstruction of power facilities and provides technical supervision services during their construction.

Objective: To provide reliable and quality power supply to consumers, improve functioning of the grid complex, provide for efficient management of the grid in Moscow, develop electricity grids by means of constructing and reconstructing power facilities located on the administrative territory of the city of Moscow.

The service area of the branch office is 1081 km2. Moscow High-voltage Networks of PJSC MOESK serve 113 substations, 78 transition points, 1123.34 km of aerial lines of 35-220 kV, 945 km of cable lines with voltage of 110-500 kV. The volume of the grid exceeds 216,452.48 TEU. The total number of staff employed by the branch exceeds 1600 people.

Moscow High-voltage Networks are subdivided into 10 District High-Voltage Networks (DHVN), which represent the main structural unit and operate feeding centers. The DHVNs are distributed according to territories of district administrations in Moscow. Maintenance and servicing of high-voltage cable lines of 110-500 kV are carried out by staff of five specialized units.


Moscow Cable Networks

About the Branch

Moscow Cable Networks is a branch of the Public Joint-Stock Company Moscow United Electric Grid.

The history of Moscow Cable Networks spans almost 120 years of successful operation. It was first created in 1897 as Electric Lighting of 1886 Company’s subdivision - cable transformer department. The department carried out construction and maintenance of electric grids.

Despite the hardships of WWI, the Russian Revolution and the Civil War, the energy sector of Moscow and Moscow Region was developing. It was here that the plans for electrification started, which later turned into Lenin’s GOELRO Plan.

MOGES Trust was created in Moscow in 1922. The cable networks of MOGES were divided into seven network districts. The company employed about 500 people. They maintained some 3300 km of cable lines, 500 km of aerial lines, 200 distribution stations and more than 3000 transformer substations.

By the tenth anniversary of the GOELRO Plan, more than 3720 mln kWh of energy was transmitted across the lines. By 1940 the total length of underground cable networks amounted to 5040 km.

During the war Mosenergo specialists, including some of the cable network specialists were employed in the 4th accident and rescue regiment of the Moscow Anti-Aircraft Defense system and the 8th separate Engineering anc Construction Battalion at the Western Front Special Assignment Office. They built electric defense lines at the frontline.

After the war, Moscow Cable Network staff ensured reconstruction and further development of the capital. They also completed their work at the time of expansion of Moscow territories in the middle of the 20th century. In 1971 Moscow Cable Networks were awarded the Order of October Revolution.

Moscow Cable Networks continued working reliably in the years after perestroika. OJSC Moscow City Electric Grid Company was founded on the base of OJSC Mosenergo on April 1, 2005. During the reform of 2008, OJSC MGEsK merged with OJSC MOESK, and since July 1, this is the largest branch of the company with the historic name of Moscow Cable Networks.

Today the branch maintains electric grids of 0.4-35 kV of the total length of 62,000 km and over 15,000 transformer substation and distribution points. As of 2016 the branch employed around 4250 people.
